Wordpress - WordPress Query and Database

Identify the error in this query:

$args = array('cat' => '5', 'posts_per_page' => 'ten');
$query = new WP_Query($args);

A'cat' should be category slug, not ID

B'posts_per_page' cannot be used with 'cat'

C'cat' parameter is invalid, use 'category_name'

D'posts_per_page' should be an integer, not a string

Step-by-Step Solution

Solution:

Step 1: Check 'cat' parameter usage
'cat' expects a category ID as integer or string number, so '5' is valid.
Step 2: Validate 'posts_per_page' value
'posts_per_page' must be an integer, but 'ten' is a string word, causing error.
Final Answer:
'posts_per_page' should be an integer, not a string -> Option D
Quick Check:
posts_per_page = integer required [OK]

Quick Trick: Use integers for posts_per_page, not words [OK]
